really? abec ratings have got jack shit to do with the ball used, balls are graded on a different spec, you are comparing your abec 5 bearings to the other companies abec 1 bearings and telling us your bearings are considerably better!!, when actually a wheel fitted with your bearings will rotate at exactly the same speed, and in reality due to the application as an rc car wheel bearing an abec 1 bearing is a better choice than a higher abec spec.
